Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully below. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Example one

Referring to fig. 1 and 2, the present invention provides a safety belt suspension device for suspending a safety belt 200 in a high pressure chamber to realize the "high hanging low use" of the safety belt 200, the safety belt suspension device 100 includes at least one section of a hanging rod 10 and at least two hoops 20, the two hoops 20 are used for connecting two different beams 30 of a roof of the high pressure chamber, and two hoops 20 are respectively connected to two ends of the hanging rod 10.

Referring to fig. 4, after the hoops 20 are installed on the cross member 30, the hanging bar 10 is installed on the two hoops 20, the safety belt 200 can be hung on the hanging bar 10, and the safety belt 200 is fastened on the body of a person, thereby realizing the purpose of hanging the safety belt 200 high and low.

If the safety belt hanging device needs to be moved to other high-pressure chambers for use, the anchor ear 20 is detached from the cross beam 30, the hanging rod 10 is detached from the anchor ear 20, and the safety belt hanging device can be mounted to other high-pressure chambers for use, so that the moving position can be realized.

For example, different high pressure chambers, and different distances between the two cross beams 30, different lengths of the hanging rods 10 can be selected to be combined with the hoops 20.

Referring to fig. 1, in the present embodiment, the safety belt hanging device 100 includes a hanging rod 10a and two hoops 20a, the two hoops 20a are used for connecting two adjacent cross beams 30 of a roof of a high pressure chamber, and two ends of the hanging rod 10a are respectively connected to the two hoops 20 a.

The hanging rod 10 is made of stainless steel material, which has high strength and can better support the weight of the safety belt and the person.

The diameter of the hanging rod 10 is 1cm-5cm, so that the diameter can ensure good bearing performance, and not too much material is consumed, thereby saving the cost. Of course, the diameter of the hanging rod 10 can be larger, and the larger the diameter, the better the bearing capacity.

The anchor ear 20 is made of stainless steel material, which has high strength and can better support the weight of the safety belt and the person on the hanging rod 10.

The two anchor ears 20 are used for connecting two adjacent cross beams 30. The length of the hanging rod 10 is slightly larger than the distance between the two cross beams 30, so that the hanging rod 10 has better bearing performance. Of course, the two anchor ears 20 may also be connected to two non-adjacent cross beams 30, for example, a cross beam 30 is spaced between the two cross beams 30 respectively connected to the two anchor ears 20, and at this time, the length of the hanging rod 10 is longer, and the longer the hanging rod 10 is, the lower the load-bearing performance thereof is. The load-bearing capacity of the cloth rail 10 can also be increased by increasing the diameter of the cloth rail 10.

Referring to fig. 1, the hoop 20 includes a first plate 21 for abutting against the bottom surface of the beam 30, a second plate 22 extending vertically from a first end of the first plate 21 for connecting to the side surface of the beam 30, and a third plate 23 extending vertically from a second end of the first plate 21 for connecting to the hanging rod 10, wherein the third plate 23 and the second plate 22 extend in opposite directions of the first plate 21. The anchor ear 20 with the structure can be combined with the cross beam 30 more stably and has lower cost.

Referring to fig. 1 and 3, the second plate 22 has a first threaded hole, and a screw 25 is threadedly mounted in the first threaded hole and threadedly connected to the cross beam 30, so that the second plate 22 is connected to the side surface of the cross beam 30. The screw 25 is, for example, a screw, a bolt, or the like. Preferably, bolts are used, which are fastened after being installed into the cross member 30, after which the first nuts 221 are installed. A first washer 222 may also be disposed between the first nut 221 and the second blade 22.

The third sheet body 23 is provided with a second threaded hole, the end of the hanging rod 10 is provided with an external thread 27, and the hanging rod 10 is installed in the second threaded hole in a threaded mode and is connected with the third sheet body 23 through the thread. Of course, the hanging rod 10 can be connected to the third plate 23 by other means, such as fastening. The end of the hanging rod 10 is fastened by a second nut 231. A second washer 232 may also be disposed between the second nut 231 and the second blade 22.

Referring to fig. 2 and 3, the diameter of the end of the hanging rod 10 is smaller than the diameters of the other parts, so as to ensure that the hanging rod 10 can be easily screwed with the anchor ear 20 when the diameter of the hanging rod is larger.

Example two

Referring to fig. 2, the seat belt suspension apparatus 200 of the present embodiment is substantially similar to the first embodiment, except that the seat belt suspension apparatus 20 includes two hanging rods 10b and four hoops 20b, that is, a first hanging rod 10b1, a second hanging rod 10b2, a first hoop 20b1, a second hoop 20b2, a third hoop 20b3 and a fourth hoop 20b4, the second hoop 20b2 and the third hoop 20b3 are connected to the same cross beam 30, the first hoop 20b1, the second hoop 20b2 and the fourth hoop 20b4 are respectively installed on different cross beams 30, two ends of the first hanging rod 10b1 are respectively connected to the first hoop 20b1 and the second hoop 20b2, and two ends of the second hanging rod 10b2 are respectively connected to the third hoop 20b3 and the fourth hoop 20b 4.

Specifically, the cross beam 30 includes a first cross beam 31, a second cross beam 32 and a third cross beam 33 which are adjacent to each other in sequence, the second hoop 20b2 and the third hoop 20b3 are connected to the second cross beam 32, the first hoop 20b1 is connected to the first cross beam 31, and the fourth hoop 20b4 is connected to the third cross beam 33.

Specifically, the first hanging bar 10b1 has a gap with the second hanging bar 10b 2. Therefore, the two hanging rods are not contacted with each other, too far separation is realized, the hanging rods can be ensured to have enough installation space due to the fact that the two hanging rods are not contacted with each other, the two hanging rods are ensured to correspond to the same height during installation due to the fact that the two hanging rods are not separated, and the consistency of the two hanging rods is ensured.

For example, the gap is 1mm to 3 mm.

Of course, it will be appreciated that if the high voltage cabinet is larger in size, the length of the harness hanger 100 is also larger so that the harness 200 carrying the person can be moved along the rail 10 adapted to the length of the high voltage cabinet while the person is walking in the high voltage cabinet.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
